About photodiode array
Where to Find Photodiode Array Suppliers?
China serves as a central hub for photodiode array manufacturing, with key production clusters in Shenzhen, Beijing, and Dongguan driving innovation and volume output. Shenzhen-based suppliers dominate the electronics supply chain, leveraging proximity to semiconductor foundries and logistics networks that enable rapid component distribution across Asia and globally. The region’s industrial ecosystem supports high-mix, low-volume production ideal for specialized optoelectronic components like photodiode arrays used in medical imaging, spectroscopy, and fiber optic communication.
Beijing contributes strong R&D capabilities in InGaAs and Si-based photodetectors, particularly for extended wavelength ranges (800–1700 nm), while Dongguan excels in integrated fiber-pigtailed solutions tailored for telecom applications. These regional specializations allow buyers to source from vertically integrated facilities offering wafer processing, packaging, and optical alignment under one roof. Average lead times range from 15–30 days for standard configurations, with localized supply chains reducing material costs by up to 25% compared to Western equivalents.
How to Choose Photodiode Array Suppliers?
Effective supplier selection requires rigorous evaluation across technical, operational, and transactional dimensions:
Technical Specifications & Compliance
Verify spectral response range (e.g., 800–1700 nm for InGaAs arrays), active area dimensions (e.g., 50µm to 1000µm), and dark current performance. Confirm adherence to international standards such as ISO 9001 for quality management and RoHS for hazardous substance compliance. For export-controlled or telecom-grade components, ensure product traceability and conformity with destination market regulations.
Production and Quality Control Infrastructure
Assess core competencies through measurable indicators:
- On-time delivery rates exceeding 90% indicate reliable production planning
- Response times under 3 hours reflect dedicated customer support teams
- In-house testing protocols for responsivity, linearity, and noise characteristics
Prioritize suppliers with documented reorder rates above 20%, signaling customer satisfaction and consistent yield performance.
Procurement Flexibility and Transaction Security
Evaluate minimum order quantities (MOQs) and pricing scalability. Several suppliers offer single-piece sampling at competitive rates (as low as $0.17/unit), enabling cost-effective prototyping. For volume procurement, confirm availability of tiered pricing based on lot size. Utilize secure payment mechanisms and request sample validation before full-scale orders to mitigate risk.
What Are the Best Photodiode Array Suppliers?
| Company Name | Location | Main Products | Price Range (per unit) | Min. Order | On-Time Delivery | Avg. Response | Reorder Rate | Annual Online Revenue |
|---|---|---|---|---|---|---|---|---|
| Shenzhen Pengying Electronics Co., Ltd. | Shenzhen, CN | ICs, Diodes, Linear Amplifiers | $0.17–$20.63 | 1–10 pieces | 100% | ≤1h | 23% | US $50,000+ |
| Beijing Lightsensing Technology Ltd. | Beijing, CN | InGaAs PIN Photodiodes | $19.50–$353 | 1–5 pieces | 100% | ≤3h | <15% | US $2,000+ |
| Dongguan E Tech Fiber Optic Telecom Co., Ltd. | Dongguan, CN | Fiber Optic Pigtails, Diodes | $2–$30 | 1–100 pieces | 100% | ≤1h | <15% | US $10,000+ |
| Shenzhen Secuera Technology Co., Ltd. | Shenzhen, CN | Security Inspection Systems | $3,550–$10,200 | 1 piece | 78% | ≤3h | 57% | US $120,000+ |
| Shenzhen Asia Ocean Electronics Co., Ltd. | Shenzhen, CN | Sensors, ICs, Transistors | $5.37–$1,010.52 | 1–100 pieces | 91% | ≤8h | 30% | US $10,000+ |
Performance Analysis
Shenzhen Pengying Electronics offers the broadest price flexibility and fastest response time (≤1h), making it ideal for rapid prototyping and small-batch procurement. Beijing Lightsensing specializes in high-performance InGaAs arrays with precise spectral tuning but carries higher unit costs and lower reorder engagement. Dongguan E Tech provides fiber-integrated solutions suited for telecom deployments, combining reliability with scalable MOQs. Notably, Shenzhen Secuera lists photodiode arrays within security scanning systems, indicating integration into end-use equipment rather than discrete component supply. Shenzhen Asia Ocean stands out for authorized distribution channels and original sensor offerings, supporting both replacement and OEM integration needs with strong reorder metrics (30%) and solid delivery performance (91%).
FAQs
How to verify photodiode array supplier reliability?
Cross-check claimed certifications against official registries. Request test reports for key parameters such as quantum efficiency, rise time, and crosstalk. Analyze supplier transaction history, focusing on consistent on-time delivery and post-sale responsiveness.
What is the typical sampling timeline for photodiode arrays?
Standard samples are typically shipped within 7–14 days. Custom configurations involving ball lenses, coaxial pigtailing, or specific packaging may require 20–30 days depending on complexity and workload.
Can suppliers accommodate low-volume or prototype orders?
Yes, multiple suppliers offer single-unit or 10-piece MOQs with transparent pricing starting below $0.25 per unit for basic silicon arrays. This facilitates design validation without significant upfront investment.
Do manufacturers provide datasheets and technical support?
Reputable suppliers supply comprehensive datasheets including spectral response curves, capacitance vs. voltage plots, and mechanical drawings. Direct engineering consultation is often available upon request, especially for integration into optical systems.
How to negotiate better pricing for bulk orders?
Leverage tiered pricing models by committing to larger volumes (e.g., 100+ units). Suppliers with high online revenue and proven reorder rates are more likely to offer discounts for long-term contracts. Always validate final pricing against sample performance to ensure quality consistency.
